SaltNip

I came back to the server after a month or so and found out my Transfusers aren't working anymore. I didn't change them around or anything, they're exactly how I left them, and they worked fine before. Any idea how to fix the problem?

The most recent server restart rolled back the area my friend and I are living in, we lost some progress and a lot of resources. Along with that, whatever I had in my inventory at the time was still on me after the restart, resulting in some items being effectively duplicated. For example, I had mined a ton of iron over the course of the time frame we lost, and I used a lot of it to make some tools and armor. I still have those tools and armor, but the iron is all back underground in ore form. If the general area around X: -4804, Y: 68, Z: -4471 could be rolled back to before the most recent restart we'd be grateful. I'm sorry but I don't remember the exact time. EDIT: My friend and I have decided to just throw away any duplicated items we remember having on us and redo everything we lost tomorrow. Please disregard this post, so sorry for any inconvenience I may have caused.

My friend and I were travelling around on boats looking for a place to claim. We came across a certain point along the coast where we got hit with a monumental amount of lag. I came back later, and while I can move now, I can't really do anything. There's only a few chunks loaded around me and I can't break blocks, use commands, or leave the area. I even tried "buying" an unstuck from the store, but that didn't work either. In game name is SaltNip, friend is La_Fabuleuse_E.
